Turbo boost & Intel Trusted Execution Technology question

[cmf21]

Don't understand this. How can a processor like the i7-860 have a faster turbo boost then lets say a i7-930. Could someone explain. I'm looking at processors and am confused. Is the 930 still faster without this. Also why does the 860 have this intel trusted execution technology and the 930 doesn't. Is it really necessary for lets say an office computer.

because LGA1156 will turbo +2 the first core, or +1 turbo all the cores.

LGA1366 can only +1 all the cores.

Trusted technology is another form of DRM. You dont need it to do every day computing in any scenario.

The 930 and 860 are 2 different platforms, and they each excel in different areas.

You cant ask a general question like this without specific details in what the machine will do.

Will you notice a difference between the two in windows and office2010?
No, you wouldnt even notice if you were on an AMD.

Yeah... The 860 (1156) is slightly newer platform, and Intel raised their turbo ability slightly. That doesn't mean the 860 is a better chip. It depends on what you want to do. If you overclock you'll most likely be turning turbo off anyway, so it's irrelevant. The 1156 stuff has the PCI-express controller on the processor, which in my understanding can provide a small bit of performance increase in some cases (aigo correct me if I'm wrong here). However it doesn't have very many lanes, so if you are going to run crossfire or SLI you'd want to go for the 1366 chipset. The 1366 boards also sometimes have more ram slots, and can run triple channel for more bandwidth (1156 is dual channel).

The trusted execution has no value for office use at this time. It'd be about as useful as having the top of your processor painted a pretty blue color.

Nah. 930=860 without Turbo Mode. Base clock speeds are same and performance per clock differences are negligible. The Turbo Mode for 860 and 930 are same when all cores are active, 860 just can have it higher with 1 and 2 cores.

The reason 860 has higher Turbo Mode is because it has lower TDP. Lower power processors have higher boost because the boost seems to be limited mostly by thermals. That's why the "all cores active" Turbo Mode is similar while "few cores active" Turbo are higher on them.
